Battle Cancer is a global fitness fundraising event series where teams of four — or individuals and pairs in the Hybrid 3|20 format — compete in high-intensity hybrid challenges combining strength, endurance, and teamwork. Events are held across 15+ cities worldwide including London, Glasgow, Paris, Singapore, Dubai, Barcelona, Berlin, Belfast, Miami, and Dublin. Since 2019, more than 100,000 athletes have collectively raised over $13 million for cancer charities around the world. Every pound, dollar, or euro raised counts as points on the leaderboard, making fundraising a core part of the competition alongside physical performance.
